" IMPRovEn :cn-CREAM rannzna The VSchedule referred to :i'n thesel Letters Patentan'd making part ci the same.

the following to b'e a full, clear, and exact description `of the same, reference "being had to the' accompany lng drawing` making part of thisSspeciicatiom'iu which-` p Figure -1v is a plan. y Figure 2 is in part a vertical section, and part an elevation, of myimproved apparatus. Y

Figure 3 is a section ofthe end ofthe arm g, showing the rubber' springs andtheir connection with the arm and dashers.

Figure 5 is atop `view ofthe sleeve and socket which works `the cream-can, and its connection with the crank, and also shows the stationa1'y,piu ions which prevent the dasher from turning.

, Figure 6 is a vertical section of the same. v The same marks of reference indicate similar parts i The nature of my `improvement consists in the construction, arrangement, and operation of the several parts, hereinafter fully shown and described.`

` Ifuthe drawing-" y a and. a represent the ice-cans, ,resting upon the bed l1, or they may rest upon the tloor, table, or other l convenient place.

c"c` are the oreamscans, supported by a step-bearing f at the'lower endat j, and at the upper end by the ,bearingkV i -fThis bea-ring` is attached totthe cover e,.as shown in g.2, and its outside is square, and fits liuto the socket 2, (see'g.l 6.)

d is a vertical sh'ft, to which are attached the arms shaft.- ,A

The upper end of this shaft is slotted, to receive gg,whicl1 maybe two 'or'more in number on each ,theclutch s at the lower end of th'e'pinion s.

e is the cover of the` cream-cans, and is held in posit-ion by the pins and socket e', so that, by turning the covers around,- the cans are caused to turn.

` f are the dashers or Scrapers, which scrape the Cream from the inside surface ofthe cream-cans, as

Jr. h are 4rubber springs, placed in the recess back of the dashers, so that, if the ice becomes thickon thesuiface ofthe can, the dashers willspring back,`

but will press agaiustthe cream` and scrape itoflC gradually.

Y plate l.

lis 4the plate which connects and' holds together the mechanism hereafter described. i 1 'y m fm are bosses cast on the ends of the plate l, and are bored to receive the sleeve o.`

'n n u 'n are legs attached to the bottom` of the tops of the ice-cans, as shown in figs. land 2.

o o are sleeves, running through the bosses m fm.

The lower ends of these sleeves form the socket '2, and the`arms p are made fast to the upper ends, as shown in figs. 1, 5, and 6. W

r is a bail or handle, for convenient-ly handling ,the plate.

This handle is secured to the upper end ofthe pinions s, so as to prevent their turning.

` tis the driving-shaft, Working in the bearings t' t'. fue are bevel or ruiter-gears, one of .which is attached to one end of the shaft t,`the other being at-` tached to the vertical shaft x, so as to` gear together. 'w is aerank or crank-wheel, attached to the upper end of the shaft x. Y w is the crank-piu. y z z are connecting-rods, by which motion is communicated from the crank-wheel w to the arms p.

y is a balance-wheel, by which the irregular motion of the machine is equalized.

The operation of my improvement is as follows: The `requisite amount of cream "is placed in the creamcau c, and the cover e put on, as shown in Y fig. 2..

The annular space around the cream-@anis filled with the freezing-material, and the plate l properly placed iu the position shown in figs. 1 and 2. 1t will be seen that the square socket 2, fitting the bearing k,'the outside of which is also square, and the clutch s', fitting the slot in the upper` end of the shaft il, and the other mechanism connected as shown and described, motion being communicated to the apparatus by turning the crank 3, the bevel-gears e' andv the wheel 'or crank w will revolve, and, by means of the connecting-rods z z', cause the armsl p to oscillate, turning the cream-,cans partly around backward and forward, while the shaft d, the arms g, and dashers f are held stationary by the stationary pinion s.

- In order to-hasten the freezing, it Ais desirable Their lower ends are'slotted,so .as to vfit the For this purpse'the flashers f are adjusted, by f or should the layer of crenmbeeome thick by standing, the rubber springs will'yield and allow the flashers to move back,` so as to pass over'such irregular surfaces, and to press against and scrape ofi' such thick layers of cream gradually.

Fig. 2 is :L View with the eau-covers removed.

The mechanism not fully shown in a is the same as that in a, and any number of eens may be operated together, being connected by connecting-rods like z to arms like p. y

What I claim as my invention, and desire to secureby Let-ters Patent, is

The plate l, the connecting-rods z z, the arms p', the sleeve and socket o :md .2, the stationary ypinion and clutch s and s', the bail r, :md legs n, the whole being constructed, arranged, and operated substem tially as shown and described, and for the purpose specified.
